Interxion to Build Data Centres in Vienna and Stockholm

AMSTERDAM 5 March 2014. INTERXION HOLDING NV (NYSE: INXN), a leading European provider of cloud and carrier-neutral colocation data centre services, today announced that in response to continued customer demand, it will construct new data centres in Vienna and Stockholm.

In Vienna, Interxion will build its second data centre (“VIE 2”) in multiple phases and is expected to provide up to an additional 5,500 square metres of equipped space and approximately 11 MW of customer available power when fully constructed. The first phase is scheduled to open with approximately 600 square metres in the fourth quarter of 2014 and the second phase of approximately 600 square metres of additional capacity is scheduled to open in the first half of 2015.

“Vienna is a key hub servicing both Eastern and Southern Europe in addition to domestic demand in Austria. As the leading connectivity-rich player in Austria, Interxion has signed key customers to further develop its growing Pan-European cloud and connectivity communities of interest,” said David Ruberg, Interxion’s Chief Executive Officer. “The VIE 2 project is being built in response to customer orders.”

The VIE 2 data centre is adjacent to Interxion’s existing facility in Vienna, providing access to nearly 100 carriers, direct access to the Vienna Internet Exchange, and existing communities of interest. The capital expenditure associated with the construction of the site and the first 1,200 square metres of VIE 2 is expected to be approximately €25 million and will have access to approximately 2.4 MW of customer power.

In Stockholm, Interxion will construct its third data centre (“STO 3”) which is expected to provide approximately 900 square metres of equipped space and approximately 1.5 MW of customer power. STO 3 is scheduled to be operational in the fourth quarter of 2014.

“Interxion continues to experience strong growth across multiple communities of interest in Stockholm, and we are again expanding our campus in response to customer orders,” continued Ruberg.

The STO 3 data centre is being constructed on Interxion’s Stockholm campus at Kista. The location provides access to over 45 carriers and ISP’s currently available on the campus and direct access to the Netnod and STHIX Internet Exchanges. The capital expenditure associated with the construction of STO 3 is expected to be approximately €12 million.

Interxion also takes this opportunity to provide updates on the status of other construction projects:
